Answer:
<BCD = 128, <ECD = 52
Step-by-step explanation:
(3x + 5) + (x + 11) = 180
4x + 16 = 180
4x = 164
x = 41
<BCD is complimentary to <ACE which is (3x + 5). (3 * 41 + 5) = 128
<ECD is complimentary to <ACB which is (x + 11). (41 + 11) = 52.
Minutes are equal to 1/60ths and seconds are equal to 1/3600ths so
-128+30/60+45/3600
-128.5125
-128.513° (to nearest one-thousandth of a degree)
Answer:
Step-by-step explanation:
the y- intercept is at -3 so is either
y= x-3 or y=2x -3
the x-intercept is at 2 so when y=0, x must be 2
0= x-3 so x=3
0=2x-3 so 2x=3 and x=3/2
in conclusion none of the equations given are the graphed
FYI the equation for the graphed line is
y= 3/2 x-3

12)64°
Step-by-step explanation:
8)180-125=55
9)90-55=35
10)180-125=55
11)180-111=69
12)45+69=116
